Objectives: To evaluate surgical outcomes of using a double uterine segment tourniquet in obstetric hysterectomy for bleeding control in patients with placenta accreta spectrum.
Methods: Retrospective case-control study conducted at the Central Hospital of San Luis Potosi, Mexico. Patients with the diagnosis of placenta accreta spectrum who underwent obstetric hysterectomy were included. Two groups were formed: in the first, a double uterine segment tourniquet was used; and in the second, the hysterectomy was performed without a tourniquet. Primary surgical outcomes were compared.
Results: Forty patients in each group were included. The use of a double uterine segment tourniquet had lower total blood loss compared with the non-tourniquet group (1054.00 ± 467.02 vs. 1528.75 ± 347.12 mL, P = 0.0171) and a lower drop in hemoglobin (1.74 ± 1.10 vs. 2.60 ± 1.25 mg/dL, P = 0.0486). Ten patients (23.80%) in the double tourniquet group required blood transfusion, compared with 26 (65.00%) in the non-tourniquet group (P = 0.0003). Surgical time did not show a statistical difference between groups.
Conclusion: The use of a uterine segment tourniquet in obstetric hysterectomy may improve surgical outcomes in patients with placenta accreta spectrum with no difference in surgical time and urinary tract lesions.
